Professional blown fiber optic cable

Blown fiber optic cable is a specialized, air-jet installed solution that allows efficient, long-distance, and low-stress deployment of fiber in microduct systems.

What is Blown Fiber Optic Cable?

Blown fiber optic cable, also known as air-blown or jetting fiber, is designed to be installed into pre-installed ducts using compressed air. This method allows the cable to be "blown" through microducts over long distances without physical pulling, reducing stress on the fibers and minimizing the risk of damage or signal loss . It is particularly effective in densely built-up areas, data centers, and complex duct networks where traditional pulling methods are impractical .

Key Features of Professional Blown Fiber Cables

• Lightweight, high-drag jacketing for long-distance blowing .
• Mechanical strengthening to meet industry interconnect standards .
• Flame-resistant options for riser and plenum-rated installations .
• Water-blocking components to protect fibers from moisture .
• Compatibility with microducts (e.g., 6 mm ID) for high-density pathways .
• Support for high fiber counts (up to 2,304 fibers in some systems) and multiple Ethernet architectures (10G, 40G, 100G), .

Advantages Over Traditional Pulling

• Reduced installation stress on fibers, lowering the risk of microbends or breaks .
• Faster deployment and longer continuous runs, sometimes several kilometers in a single blow .
• Flexibility to upgrade or add fibers later without major civil works .
• Suitability for complex or rural duct networks, including overhead and subduct installations .

Installation Process

Professional installation involves:

1. Planning and duct analysis to determine pipe diameter, route length, and cable type .
2. Use of specialized blowing machines that generate controlled airflow to guide the cable .
3. Testing and commissioning to ensure cable integrity and optimal network performance .

Applications

• Data center interconnects and horizontal/backbone distribution .
• Passive Optical Networks (PON) and enterprise networks .
• Long-distance or high-density fiber upgrades in existing duct systems .
